a -WEED ExTaAcron;

Application filed November 21', 1923. seriai No. 673,085 i r This invention relates to improvements in weed extractors and more particularly to -machines of this kind of the rotary type.

The objects of the invention are to provide a rotary'weed extracting machine of light anddurable construction and in which the weeds are removed from the "ground by means ofrotating wires.

Further objects of theinvention are the provision of'a weeding machine of this character that will more efficiently perform the work required of it and in which the extractors, being rotatable above" and below the ground, are, in operation, automatically kept clear of weeds and thusprevented from being clogged. i 1 I With the foregoing and other objects in view, the invention consists'essentially in the "novel arrangement andconstruction of parts described in the present specification and illustrated by the accompanying drawings that form part of the same. 7 7 Referring now to the drawings, in which like characters of reference indicate 7 corresponding parts in each figure.

Figure 1 is a top plan view of an embodimentof my device. g r a Figure 2 is a side elevatlon.

Figure 3 is a plan view of the rotatable weed extracting means. c.

Figure 4,1s an end view of th'esame.

In the drawings, A designates an embodiment of my improved rotary weeding mato draw'the machine. a The weed extractors carriedby'the ma-' 7 chine are attached in the rear of and'sub chine as a wholecomprising a transversely extending shaft 10 having keyed at each end thereon tractor wheels 11 and 12 and adapted to carry intermediate'of said wheels a 'supporting bracket 13 provided with arms 1a :and 15 adapted tovloos'ely'engage with the shaft 10. -On this bracket 13 ismounted a drivers seat 1 6fand a platform 16 while link-connected to-the front of it are hounds 17 and'18 whereby horses can-be attached stantially on each side of the drivers seat andare also so arranged 7 that the one in front slightly overlaps the one further in the rear, thus forming an unbroken line of extraction between the wheels.

These weedfextractors comprise the sup porting arms l9and 20 and 21 and 22, respectivelnthe forward ends of. the arm 19 and 21 being supported on'the bracket13 and B 1 the forwardends of'the arms 20 and 22being loosely mounted on the shaft 10." The outer extremities of these arms are designed to carry, the rotatable shafts '23 and 24,

providing means for tightening or loosening the wires 28 and also making it com-' 5 'paratively easy for a'wire, when lbroken,-to i be renewed. Y 1 i v The numeral 28 indlcates wlres of su table formation and strength strung on these hook 'members 27 anddesigned, when rotated, to eradicate the weeds from the ground.

,To' rotate the castings 25, sprocket wheels 29 and 30 are provided on the shafts 23 and 24 and these sprocket wheels are'in turn connected by chainsp3l and '32 torsprocket wheels 33 and 34; onthe shaft 10. Q, I I

Infloperatiomit willbe seen that on the machine being moved forward and the axle 10' rotatedthe sprocket wheels 33 and 34L will rotate, operating,' through the chains 31 and 32 and the sprockets 29 and 30, the shafts 23 i and 24 i vithgthe wire-connected castings25 thereon to engage with the earth and the wires bein'g preferably barbed to efficiently extract the Weedstherefromf t a I A feature of my improved weederis'the 99 prevention 'of clogging of the extractors,

this being accomplishedby the fact that they are adapted to rotate above the ground as well as ,under it,"thereby, in their rotation above the ground, automatically clearing themselves of any accumulation ofweeds encountered in their travel beneath the ground.

As manychanges could be made in the I i i above construction and many ap ar ntl 10 0 widely different embodiments of my 1nven tion, within the scope of the claims,'constructed without departingfrom' the spirit "or scope thereof, it is intended that" all matter contained in'the accompanying. specifica m? *tion and drawingsshall be'interpreted as illustrative and not in a limiting sense. 1

claim as my ventionim A weed extractor comprising" a shaft, nuts for the hook members and strands of means for rotating the shaft, a star-shaped Wire or the, like rigidly connected at each Casting, having a plurality of threaded oriend to said hook members and Weed eradicat- 10 fices in the points thereof, rigidly mounted ing means formed'on said wires. 1 i 1 at each end of the shaft, hook members In Witness whereof I have hereunto set I formed with threaded stems adapted to enmy hand. 7 gage with said orifice, retaining, adjusting V RUSSELL MILLS.
